Technical Field

[0001] The utility model relates to the technical field of charging devices, in particular to a brush block telescopic mechanism for a charging pile. Background Technique

[0002] An Automated Guided Vehicle (AGV) is a transport trolley equipped with electromagnetic guidance or optical guidance and other automatic guidance devices. It is powered by a battery, can travel along a specified guidance path, and has programming and parking selection devices, safety protection, and load transfer functions. In modern industrial production, AGVs have been widely used in fields such as logistics warehousing, manufacturing, post offices, libraries, port terminals and airports, tobacco, medicine, food, chemical industry, hazardous places, and special industries. An AGV charging pile is a charging device for AGV trolleys. The AGV trolley moves to the charging pile under the control of a computer, and the charging connector of the AGV trolley is docked with the brush block protruding from the housing of the AGV charging pile to enable charging.

[0003] The cable of the existing charging brush of the charging pile cannot return to its original position when the charging brush is retracted. In the Chinese patent literature database, the patent with the application number 202122962177.8 discloses an AGV charger brush block telescopic mechanism that uses a drag chain to store the cable to avoid potential safety hazards caused by internal cable entanglement. In actual use, when the cable is long, the storage requires a large amount of space and has poor practicability. Summary of the Invention

[0022] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a charging pile brush block telescopic mechanism, including a support frame 1, a charging brush 2 horizontally slidably arranged inside the support frame 1 through a linear driving member 3, and a guiding mechanism 4 for restricting the linear sliding of the charging brush 2. In this embodiment, the support frame 1 is of a cuboid structure, the top end of the support frame 1 is provided with an openable top cover 102, an opening 101 for accommodating the charging brush 2 to extend out is penetrated through the front end of the support frame 1, the linear driving member 3 can specifically be an electric push rod horizontally installed inside the support frame 1, and the output end of the electric push rod is fixedly connected to the end of the charging brush 2 far away from the opening 101, and the charging brush 2 is pushed to horizontally slide inside the support frame 1 by the telescopic movement of the electric push rod.

[0023] In this embodiment, the guiding mechanism 4 includes two guiding rods 401 fixed to one end of the charging brush 2 and a linear bearing 402 fixed inside the support frame 1. The guiding rods 401 are slidably connected to the linear bearing 402, which can play a role in guiding and limiting. Further, the guiding mechanism 4 can also be set as a structure of a slide rail and a slide groove.

[0024] An end cover 6 is provided inside the opening 101. The top ends on both sides of the end cover 6 are rotatably connected to the support frame 1 through a pin shaft 601. The bottom ends on both sides of the end cover 6 are rotatably connected to the charging brush 2 through a connecting arm 7. One end of the connecting arm 7 is rotatably connected to the bottom end of the end cover 6, and the other end is rotatably connected to the top end of the side wall of the charging brush 2. When the charging brush 2 extends, it pushes the end cover 6 to turn upwards around the pin shaft 601. When the charging brush 2 retracts, it pulls the end cover 6 to turn downwards around the connection part of the support frame 1, so that the end cover 6 overlaps on the front end of the charging brush 2 of the support frame 1, playing a role of shielding and protection and improving safety.

[0025] A winding mechanism 5 for winding the cable is provided inside the support frame 1. The winding mechanism 5 includes a reel 501 rotatably installed inside the support frame 1, a gear 502 fixed to one end of the reel 501, and a rack 503 fixed to the charging brush 2. The rack 503 meshes with the gear 502. During use, one end of the cable is connected to the charging brush 2, and the other end is wound around the reel 501 and then connected to the inside of the charging pile. The rack 503 moves horizontally back and forth synchronously with the charging brush 2, and then drives the gear 502 to rotate forward or backward. When the charging brush 2 extends, the reel 501 unwinds. When the charging brush 2 retracts, the reel 501 winds up, which can realize the automatic winding and unwinding of the cable, meet the use requirements, and avoid the cable from being messy at the same time.

[0026] In this embodiment, a guide wheel 504 is rotatably installed on one side of the support frame 1 close to the rack 503. The guide wheel 504 is located below the rack 503, and the guide wheel 504 is in rolling connection with the bottom end of the rack 503. The gear 502 and the guide wheel 504 clamp the rack 503 in the middle, which can play a role in supporting and limiting the rack 503.

[0027] In this embodiment, limiting plates 5011 are fixed to both axial ends of the reel 501, which can play a role in limiting the cable, so that the cable is wound around the reel 501 between the two limiting plates 5011.

[0028] Working principle: When the linear drive 3 extends, it pushes the charging brush 2 to move to one side, passes through the opening 101 and moves out to the outside to dock with the charging connector of the AGV car for charging. At this time, the rack 503 moves synchronously with the charging brush 2, and the gear 502 meshes with the rack 503, driving the gear 502 and the reel 501 to rotate, realizing the automatic unwinding of the cable. After charging is completed, the linear drive 3 contracts, driving the charging brush 2 to retract into the interior of the support frame 1. The charging brush 2 drives the end cover 6 to rotate around the pin shaft 601 through the connecting arm 7, and abuts against the opening 101 for sealing and blocking. At the same time, the rack 503 drives the gear 502 and the reel 501 to rotate in the reverse direction, automatically winding the cable around the reel 501 to avoid accidents caused by the cable being messy.
